A Diesel Particulate Filter (or DPF) captures soot particles, and is an essential component of any modern diesel engine, but can become blocked over time, and replacement isn't cheap. Fortunately many of our friendly, expert garages across Harringay offer chemical cleaning as an alternative, so you can receive competitive Mercedes quotes FAST.

Excellent service. Picked up and delivered the car in the given time. Car also cleaned. Thanks Daniel for your honest and excelllent service

Daniel's friendliness and customer service is second to none. Audi A3 cambelt kit, water pump and coolant fitted. Work completed as scheduled at the price estimated. Car cleaned inside and out too. Can't fault the whole experience, I'm so happy I've found a mechanic I can trust.

Car Technic did a great job. I am very satisfied. Will definitely come back.
One of the biggest factor why this job felt so satisfying is the guy who took care of it: Daniel. He delivered everything he promised on time and with the best possible quality. Thank you so much.

Mike was very helpful and polite. He had excellent customer service skills. With extensive knowledge of car mechanics and a quick turn around time I would definitely recommend him to others. I will be contacting Mike in the future for all my car repairing needs.

My speed dial was not working on my Vauxhall Corsa and I wanted to find a place to fix this problem. I went on line on to who can fix my car. I did not have to wait long Mike from Sphynx Vehicle repairs responded back within the hour and left me a number that I could call. Mike was polite an explained the process that my car was to have a diagnostic test he got back to me straight away with the results and choices which was on offer and how much each of these was going to cost and how long this would take after making my decision Mike kept me informed and updated me on the progress and when my car was going to be ready. The invoice listed the works carried out the speed dial is now fixed. I will be using this company in future the customer service is very good and Mike is contactable and is always ready to explain the full issues occurring with your car I would recommend him to my friends and family members

I finally found a great mechanic next door! He offered me to collect my car at my address, then showed me all the parts which I needed to be replaced, giving me different options of parts about quality and prices. He kept me updated about the work progress and He took only one day to fix it. ( Only because the parts wasn't available straight away). Now my car runs perfectly without any problems. I definitely suggest this garage!

I got Mike from Sphynx Vehicle Repairs for a computer diagnosis and i was very happy about him. He gave me a very specific explanation about what is wrong with the car and the costs of repair. Next time i will have a problem with my car, i know where to go. Recommend him 10/10.

If it would be possible I would give zero star for this garage. Outrageous service, I am not sure if I can call that "service".
The owner of this garage is extremely rude, phlegmatic and DISRESPECTFUL! And according to my opinion he is probably racist towards Eastern-European people!
First, we discussed the time and the date when for a 1 and half hour work to fix my car. But when I arrived there at the first time (in the arranged time), they did not fix my car because they said I am late.
I am just saying we were communicating via this website in chat form, so I have everything in written form. I can prove everything.
I was not late. I thought I can give them a second chance (because of their really good price), so we discussed the time and date again via this website, and I went there again in the arranged time, but the same thing happened, but this time the owner of the garage was even yelling to me!
Their price offer was so good (£120 cheaper from any other offer), thus I gave them a third chance.
But this time I called them before I go there (since I did not want to waste my time and fuel again), they confirmed I can go immediately and they will fix my car (they said it will take 1 and a half hour), but when I arriced there they said I was late again. I arrived there at 10AM and they said I need to leave my car there until 2PM. I told them I work with my car, the only reason I came here on this day in this time because they confirmed I can come here now for 90 minutes work. I told them again, I work with my car, then I got the usual answer from the owner of the garage: "not my problem".
Then I left them without any word.
They wasted my time and fuel, 3 times and my car is still not fixed!
The owner has zero customer service skills, zero flexibility towards customers (his answer to everything: "not my problem, is it?" or "not my business, is it?").
I would never recommend this garage to anyone.
Seriously anyone who reads this: AVOID THIS GARAGE!

Szabolcs, Vauxhall Meriva

I don't usually use sites like these to get my car repaired, but i was desperate, so i ended up using this site.
Out of all of quotes i got, these guy's came out by FAR the cheapest, at least £100 cheaper than everybody. I thought at first there was a catch, like one of the previous garage's i called on here, they quoted £220 for just the labour and not the parts. But NO these guy's quoted me on exactly how much it would cost !
Quick service, no messing around. They even fitted in some missing clips on my front bumper which was nice of them.
And also to top that i asked them how much it would cost to replace my back light bulb and they did that for free too !
Great, quick, reliable service. Will definitely be seeing these guy's again if something (Touch wood nothing) goes wrong !

Paul was very helpful even to the point of picking up my car and returning it. They did a great job. In a good time. I'm just sorry my insurance company were slow on paying up their end. Hopefully now resolved.
I will be sending my mums car to him soon.
Happy to recommend them to others.

No I would not recommend this garage.
We paid for the vehicle delivered to your garage on the 23/03/16 for a Cam Belt change, we also had the Clutch replaced and Water Pump whilst you had the vehicle, with the understanding that we needed the vehicle back in time for a contract job we was doing. We picked the vehicle up and paid £1050.00 in which we paid when the invoice should have been for £950.00 because we supplied the cam belt kit and drive belt. We paid again for the vehicle to be returned to your garage because the battery went flat and didn’t start on the 30/03/16 and then we had to hire a splitter van to replace ours, for 3 days at a rate of £130.00per day. We paid to have the vehicle to be picked up after you telling me that it was the battery at fault, so we agreed to offset the over payment for a new battery. We used the vehicle on 02/04/16 and that evening the vehicle lost lighting it went dim first and then all the warning lights started to come on. We lost the vehicle hire £100.00 for that day of the 02/04/16, and had subcontract hire at a rate of £150.00 for the 03/04/16 for not having a vehicle to for fill our contract. We did not return the vehicle, because of no confidence. We had the vehicle tested, and we was told that the Alternator was faulty so I replaced it myself after taking a photo of the of its position then still getting the right reading from the new Alternator the vehicle was taken to an Auto Electric Technician in which we found that your garage had put the alternator belt on incorrect so it was turning the wrong direction, so we didn’t need a battery or an alternator because the vehicle never had a starting or charging problem before it went to you plus the damage to be repaired at a cost £150.00
This is a breakdown of our invoice to you of our losses.

Car repair was done to good standard (slight delay in getting it back from them due to paint shop issues) They were polite and kept me informed throughout. Polite and friendly. Not dealership level repair but good enough for the price.

Always a pleasure dealing with these guys as legit as they come, I would recommend they be your first choice you won't be disappointed. First class service.

Brilliant garage. I needed this wing mirror very quickly as I had to go Glastonbury the next day and these guys got it done straight away. They were also friendly, honest and as someone who's had a lot of bad experiences with garage these awesome guys put me at ease. Not to mention the price was very reasonable considering some chain garages were quoting me over double! Will never going anywhere else now! Thanks again :)

Dennis, Volkswagen Golf

Very friendly and prompt service, really happy with the job. I've used these guys a few times now and will definitely use them again.

This is an excellent local garage that I wish was more local to me - but worth the journey. Joe, who runs the office side of the business, is brilliant and reassuring (my car is extremely old). There were clear explanations at every stage and all the work was fast and efficient. I highly recommend this garage

Hopefully our FAQ section has answered some of the questions you may have about diesel particulate filters, however, if you would like more information, we have the following guide help you understand more about your Mercedes Ever since 2009, the Euro 5 standard has been enforced, a rule which ensures all new diesel Mercedes must have particulate filters fitted.

These pieces of equipment were introduced in an effort to reduce the particle and soot emissions from diesel engines. Diesel Particulate filters (DPF) trap soot before it blows out of an exhaust and like any filter, it requires cleaning in order to maintain performance.

Fortunately the filter itself has self-cleaning capabilities known as regeneration.

There are two types of regeneration which can be carried out on your Mercedes.

Passive Regeneration

This process happens automatically while the exhaust is at a high temperature which will usually occur when you are driving down a motorway or quickly down an A-road. However, as many vehicles aren’t always being driven at high speeds, an alternative system for regeneration exists.

Active Regeneration

This method of cleaning the DFP is controlled by an engine management computer and happens automatically when the filter reaches 45% of its limit. The process is initiated by the fuel injection being increased which makes the exhaust heat up and therefore clear the filter. However, if your drive is a short one and the process tries to initiate, it will not be able to properly clear the filter, in this eventuality, the warning light in your car will come on.

A drive of about ten minutes at a speed of around 40mph should be adequate for the process to be successful.

Here are the signs of automatic regeneration

Cooling fans running

Increased idle speed

Deactivation of automatic stop/start

A slight increase in fuel consumption

A hot and strong smell emitting from the exhaust

The note of the engine changing
However if the regeneration is unsuccessful, the fuel which is earmarked to burnt, will have to drain into the sump.

This will result in the oil quality in your Mercedes getting worst and its level will rise.

That is why it is important that you keep an eye on your oil levels at all times as any drops, change in viscosity or mixing with other agents such as lubricant or water, can cause serious damage.

You should have an automatic sensor in your Mercedes to warn you of any impending damage, which should not be ignored as the entire engine will be at risk.

If you do ignore the DPF light the filter will reach a point where it cannot function and other warning lights will come on as other parts of the engine are effected. If the soot level reached 70-75% you have no choice but to take the car to a garage and have it manually refreshed.

What prevents automation regeneration?

Lots of small journeys

Wrong oil type

Gas recirculation malfunction

Constant low fuel level

Low additive levels
If these issues are effecting your Mercedes it is almost certain that you will need your filter replacing which is likely to cost upwards of £1000 including diagnostic and labour time.

And if you were thinking of saving all of that time and money by removing the filter completely, think again, it’s illegal to remove the DPF.

The Department for Transport states that it is an offence to remove the filter or modify the piece of equipment in a way which would result in the vehicle failing air pollutant emission standards. Breaking the law will result in the vehicle not being road worthy so if you are ever offered to have your filter removed, make sure to keep this in mind.

Every MOT now includes a check for the DPF and a smoke test from the exhaust so there is very little chance of getting away with removing the filter.

If you need to have the filter regenerated manually, you must take your vehicle to a trained professional immediately. They will initiate a process where the exhaust is heated up to a point where regeneration happens and soot is cleared from the filter.
